2 Meeting on status and plans of the LP subsystems for the LP beamtest at DESY 02/25/2008 2Franck SENÉE LP-TPC: Micromegas Panel and Cosmic Muon Trigger Micromegas panel: -Details of Printed Circuit Board -Mechanical group -Flat cables -Proposal for an assembly without the weight of electronics on the endplate -Mid 2009 Cosmic muon trigger: -Mechanical group with 5 slabs (top), similar bottom -General implantation Schedule of installation at DESY

3 Meeting on status and plans of the LP subsystems for the LP beamtest at DESY 02/25/2008 3Franck SENÉE Micromegas Panel: PCB C1: Pads layer C6: Connectors layer Stacking C1/C2: Insulation layer The layers of insulation are Nelco 7000 (Polyimide:Glass Transition Temperature = 260°C): necessary for the resistive layer 24 lines of 72 pads: 1728 pads with 2 used for supplier the HV to the grid. Routing in progess. 18 connectors of 80 pins:4 are used by FEC HV

4 Meeting on status and plans of the LP subsystems for the LP beamtest at DESY 02/25/2008 4Franck SENÉE Module Back Frame (D. Peterson) Module Mounting Bracket (D. Peterson) Micromegas Panel: Mechanical group PCB Gluing

5 Meeting on status and plans of the LP subsystems for the LP beamtest at DESY 02/25/2008 5Franck SENÉE Micromegas Panel: Connection between PCB and FEC card with flat cables The longest=200 mm, the shortest=120mm Flat cables will be ordered soon FEC + shielding

6 Meeting on status and plans of the LP subsystems for the LP beamtest at DESY 02/25/2008 6Franck SENÉE Micromegas Panel: Proposal for an assembly on the endplate Step 4: Continuation of the assembly of mechanics support of electronics Step 6: Wiring of the flat cables on the micromegas panel Step 9: All the FEC board are wired Step 10: Assembly of shielding outside and top parts support of electronics on the outside of the endplate Step 12: Disassembly of mechanics support of electronics on the module mounting bracket. The electronics is now fixed on the outside of the endplate Step 11: Wiring of mezzanine board Step 1: Assembly of the module mounting bracket on the endplate Step 2: Installation of the module back frame Step 3: Assembly of mechanics support of electronics on the module mounting bracket Step 8: Continuation of wiring flat cables on the micromegas panel and the FEC Step 5: Assembly of bottom parts support of electronics on the outside of the endplate Step 7: Wiring of the first FEC

7 Meeting on status and plans of the LP subsystems for the LP beamtest at DESY 02/25/2008 7Franck SENÉE Micromegas Panels: 7 panels mid 2009 Where to fix all it elsewhere that on the endplate? New electronic design

8 Meeting on status and plans of the LP subsystems for the LP beamtest at DESY 02/25/2008 8Franck SENÉE Cosmic Muon Trigger: 5 slabs group (top) Mechanical assembly in progress One box for slabs group with: - Temperature control (bar copper and heat pump for Peletier effect) – Readout circuit (adder and amplificator)

9 Meeting on status and plans of the LP subsystems for the LP beamtest at DESY 02/25/2008 9Franck SENÉE Cosmic Muon Trigger Slabs received on February 11 Wrapping finished OUT MPPC1 OUT MPPC2 OUT (MPPC1+MPPC2)x45 Amplificator: Gain=45 MPPC1 MPPC2 Power supply MPPC Tests in progress

10 Meeting on status and plans of the LP subsystems for the LP beamtest at DESY 02/25/ Franck SENÉE Micromegas Panels: General implantation To raise the PCMAG frame of 14cm to put the bottom slabs set

11 Meeting on status and plans of the LP subsystems for the LP beamtest at DESY 02/25/ Franck SENÉE Mid March: Mounting mechanic of 3 set slabs for cosmic muon trigger, Testing temperature control at Saclay April: Testing cosmic muon trigger setup at Saclay April: Testing of the first micromegas panel at Saclay with resistive layer May: Complete Installation (Cosmic muon Trigger + Micromegas panel) at Desy Schedule of installation at DESY
